Scenario: friend was eating some leftover ground beef from some hamburgers we cooked earlier with tortilla chips and cheese. I commented on what he was eating and he said he was eating "tacos." I disagreed because there was no tortilla shell wrapping the contents so at best he was eating nachos. Well was he eating a taco or not?

Second argument that stemmed from the first: since I argued that the shell of something is vital for the dish to be considered what it is, another friend joined in and started to argue that the filling is more important than the outer shell of something for the name. Example being that the pie filling is more important than the pie crust to be considered a pie. I need a consensus and I hope I explained this well enough. I will be here for clarification if needed.
